Workaround for CVE-2017-5715 on Cortex A73 and A75
Invalidate the Branch Target Buffer (BTB) on entry to EL3 by
temporarily dropping into AArch32 Secure-EL1 and executing the
`BPIALL` instruction.
This is achieved by using 3 vector tables. There is the runtime
vector table which is used to handle exceptions and 2 additional
tables which are required to implement this workaround. The
additional tables are `vbar0` and `vbar1`.
The sequence of events for handling a single exception is
as follows:
1) Install vector table `vbar0` which saves the CPU context on entry
to EL3 and sets up the Secure-EL1 context to execute in AArch32 mode
with the MMU disabled and I$ enabled. This is the default vector table.
2) Before doing an ERET into Secure-EL1, switch vbar to point to
another vector table `vbar1`. This is required to restore EL3 state
when returning from the workaround, before proceeding with normal EL3
exception handling.
3) While in Secure-EL1, the `BPIALL` instruction is executed and an
SMC call back to EL3 is performed.
4) On entry to EL3 from Secure-EL1, the saved context from step 1) is
restored. The vbar is switched to point to `vbar0` in preparation to
handle further exceptions. Finally a branch to the runtime vector
table entry is taken to complete the handling of the original
exception.
This workaround is enabled by default on the affected CPUs.
NOTE
====
There are 4 different stubs in Secure-EL1. Each stub corresponds to
an exception type such as Sync/IRQ/FIQ/SError. Each stub will move a
different value in `R0` before doing an SMC call back into EL3.
Without this piece of information it would not be possible to know
what the original exception type was as we cannot use `ESR_EL3` to
distinguish between IRQs and FIQs.

and then branches off to the corresponding vector entry in the main
vector table. A side effect of this change is that the main vbar is
configured before any reset handling. This is to allow the per-cpu
reset function to override the vbar setting.
This workaround is enabled by default on the affected CPUs.

Disable PIE compilation option
ARM TF does not work correctly if built with a version of gcc
that is configured to use PIE by default (e.g. Debian Stretch).
This patch identifies when such a version of gcc is being used

io: block: fix block_read/write may read/write overlap buffer
The block operations were trying to optimize the number of memory
copies, and it tried to use directly the buffer supplied by the user
to them. This was a mistake because it created too many corner cases:
1- It was possible to generate unaligned
operations to unaligned buffers. Drivers that were using
DMA transfer failed in that case.
2- It was possible to generate read operations
with sizes that weren't a multiple of the block size. Some
low level drivers assumed that condition and they calculated
the number of blocks dividing the number of bytes by the
size of the block, without considering the remaining bytes.
3- The block_* operations didn't control the
number of bytes actually copied to memory, because the
low level drivers were writing directly to the user buffer.
This patch rewrite block_read and block_write to use always the device
buffer, which the platform ensures that has the correct aligment and
the correct size.

SPM: Fix MM_COMMUNICATE_AARCH32/64 parameters
This partially reverts commit
d6b532b50f8, keeping only the fixes to
the assertions. The changes related to the order of arguments passed
to the secure partition were not correct and violated the
specification of the SP_EVENT_COMPLETE SMC.
This patch also improves the MM_COMMUNICATE argument validation. The
cookie argument, as it comes from normal world, can't be trusted and thus
needs to always be validated at run time rather than using an assertion.
Also validate the communication buffer address and return
INVALID_PARAMETER if it is zero, as per the MM specification.
Fix a few typos in comments and use the "secure partition" terminology
rather than "secure payload".

SPM: Move S-EL1/S-EL0 xlat tables to TZC DRAM
A new platform define, `PLAT_SP_IMAGE_XLAT_SECTION_NAME`, has been
introduced to select the section where the translation tables used by
the S-EL1/S-EL0 are placed.
This define has been used to move the translation tables to DRAM secured
by TrustZone.
Most of the extra needed space in BL31 when SPM is enabled is due to the
large size of the translation tables. By moving them to this memory
region we can save 44 KiB.
A new argument has been added to REGISTER_XLAT_CONTEXT2() to specify the
region where the translation tables have to be placed by the linker.
